BELEBEY VEGRANDIS IVAKHNENKO, 1973

Holotype: PIN ( Palaeontological Institute , Russian Academy of Science, Moscow, Russia) 104/50 maxillary bone with partly preserved palatine bone.

Referred specimens: SGU (Saratov Geological University, Saratov, Russia) 104/B-2020, a small complete skull that has been disarticulated ( Figs 1–6 View Figure 1 View Figure 2 View Figure 3 View Figure 4 View Figure 5 View Figure 6 ); SGU 104/B-2021, a slightly larger, complete skull ( Figs 7 View Figure 7 , 8 View Figure 8 ); SGU 104/B-2022, a large, partial skull, preorbital region not preserved. This large individual was available for study but could not be illustrated .

Horizon and locality: Upper Kazanian, Middle Permian; Bashkortostan and Orenburg regions, Southern Russia .

Diagnosis: Bolosaurid parareptiles characterized by the presence of strongly procumbent incisiform dentition anteriorly, and linguo-labially elongated, bulbous, posterior cheek teeth with strongly developed longitudinal striations. Non-dental potential autapomorphies cannot be recognized because most of the other bolosaurid taxa are known from fragmentary cranial and mandibular elements.
